When thus engaged, the blow pipe will. be in alinement with the blow head l, while the gather or blanke will be supported intermediate the open y c ions of the mold J. As motion is io io the revoliihle frame C, the blow .fill la' lowered by the engagement l with the depressed portion of the ii ek il. rl`he sections of the mold J will also be closed about the blank by the ogwrinioii of the slide O through its ene eminent with the cam O, and following these operations the valve P2 will be opened to admit blowingY air to the head I. which, passing' through the pipe H, expands the blank until it fille the mold cavities. During the blowing the blow pipe and gatherer are revolved through the medium of pinions K and lrear wheel K. The movement of the rotary frame C continues until the mold blow pipe reaches the position, 2, Fig. 2, at which point the machine is stopped.- Before reaching' this stopping point, the valve P2 is cloaed, the sections of the mold J are opened, and the blow head l is raised s0 that when the machine stops the operator can remove the blow pipe with the blown article attached thereto.

To diseneage the blown article, the glass inustbe cracked to sever it from the portion still adhering to the blow pipe. This operation freoucifitlv results in breaking` thearticle, and it is therefore one of the objects of the present invention to avoid such a result. This l accomplish by providing means for creasingv or scoring the blank after the mold is open. As shown S and S are scoring,r blades, which are pivotally mounted upon a head ".l extending between the posts E. 4T are links for rocking the blades S S upon their pivots, said links beingr connected to a slide T2 having a roll T8 engaging a cam T" upon the pedestal B. Tls is a buffer springl forming a yielding connection between the roll Ta and the slide T2. The blades S S are arranged to swing in a plane slightly below the upper end of the mold in the position which it occupies during the blowingv operation, and the mold is pref# erably provided with an annular rib or bead il in the plane which forme a slight 1groove in the glass neck. The normal position of the blades S S is such as to permit the partial opening of the in old sections, which occurs after the completion of the blowing operation. When the mold sections are thus opened, and before the comi'ilction ol the movement of the trame C, the molds are dropped by a slight depression M in the cam track lvl, and this provides clearance lor the operation of the blades S S. 'l'lxo latter are llien pressed inward through the medium of the link T', Slide T2, and

noaa-46s cam T4, pressing in the creased portion of the blank and making' a deep score. The blades are then opened again, permitting the removal of the blow pipe from which the blown article may be readily severed by cirackinp,r at the score.

As has been previously stated,` the blow pipes ai'e supported` upon the bearings R which, in order to pcrinit rotation of the pipes, are preferably roller bearing. These roller bearings lt engage a shoulder or enlargement RL upon the blow pipe and Support it in a fixed position. By continued ilse, the end ot' the blow oipe is burned oli' so as to shorten the lengt or the distance between the shoulder R2 and the lower end of the pipe, and this changes the relation of the gatherer to the mold. To avoid this change, I provide means foiadjiiSting the bearing R' to compensate for the decreased length of the pipe, the construction being preferably as follows: W is a yoke or cross head which slidably engages the posts E, and at itsI outer end carries the bearing R. W is a shaft having the pinions W2 arranged to engage rack teeth lW3 formed in a ortion of the post C. The Shaft W- is )oiirnaled in bearings in the yoke WV, and one of these bearings is provided with a clamping screw W by which the shaft may be locked in any position of adjustment. WW is a crank arm for rotating the shaft W. lith the construction ust described, Whenever the blow pipe is shortened in length, the clamp W4 may be loosened and the arm W moved to lower the yoke W, until the lower end of the blow pipe is in the proper relation to the mold.

What I claim as my invention is:

1. n a machine for blowingj glass, the combination with a revoluble blow pipe, of a reciprocating severing bladeY having its path of movement in a plane transverse to the plane of the blow pipe, and means for pressing the same against the glass intermediate the end of the blow pipe and the -fashioned portion of the blown article.

2. In a machine for blowing glassthe combination with u revolubleblow pipe, of a mold for fashioninf,T the blown article, and means operating after the disengagement of said mold for scoring; the glass intermediate tho end of the blow pipe and the fashioned portion of the blown article.

ln a machine for blowing 1glass, a blow pipe, a mold having an annular rib for detiniiugr the line oi out oft' in the blown article, and means operating after the disengagement. of said mold for scoring the glass upon said line of cut oli.

4. ln a machine for biowingir glass, the combination with a blow pipe, of a mold havinpr an annular rib for grooving the blown article in the lin(- of cnt ofi, a scoring bladey movabhl against the glass in the 130 i lane of cut off, and means for o emng and owering the mold in advance'q the operation of said scoring blade. A

5. In a.machine forl blowing glass, the combination with a blow pipe, of a mold formed of separable sections, a pair of scoring blades upon opposite sides of said mold, means for moving said blades laterally against the blown article, and means for opening and lowering said mold in advance of the operation of said blades.

6. In a machine for blowing glass, the combination with a traveling mold carrier, and a mold thereon; a blow'pipe'detachably engaging said carrier, a supporting bearing for -said blow'pipe, parallel vertical guides on said carrier, a cross head slidably engaging said guides upon which said bearing 1s mounted, and a/rack and pinion engagement between said head and guides for vertically adjusting said bearing.

7. In a machine for blowing glass, the combination with a. blow pipe, 0f a mold adapted to engage the lower end of the blow pipe, means for defining a line of cut-oil' on the glass intermediate the end of the blow pi e and the fashioned portion of the artice, and means operated in timed relation to the mold for subsequentl scoring the glass along the line of cut-o when disengaged from the mold.

i8. In a machine for blowing glass, ,the combination with a blow pipe, of a mold adapted, to engage the lower end of the blow pipe, means for defining a line of cut-ofi' on the glass intermediate ,the end of the blow pipe and the fashioned portion of the ar tic e, and means operatively positioned in relation to the mold for subsequentl scoring the glass along the line of cut-oli? In testimon whereof I affix my signature in presence o two Witnesses.
